A collection of wind turbines all in the same location and used for the generation of electricity is termed as wind farm. Some of the largest wind farms in the world can be found in the United States, three of them are located in California. These include Altamont Pass, San Gorgonio Pass and Tehachapi Pass. The Stateline Wind Project, the largest US wind farm situated in
Oregon-Washington line has a peak capacity of 300 megawatts of electricity. Accordingly, the California wind farms have many different owners and turbine types. They have built, retrofitted and occasionally dismantled since they were first installed in late 1982. Three of these areas are seeing renewed growth in 2005.
There are two proposed wind farms which have had difficult approval in Massachusetts. In
New York, there is another 40-turbine offshore wind power installation proposal in the ocean off Jones Beach, Long Island. This proposal has the support of a number of local and national environmental groups and Long Island Power Authority and the Governor of New York. Also, the first coastal wind farm was launched in New Jersey in December 2005. However, as of May 31, 2006, the FAA (Federal Aviation Administration) has stopped construction at 15 midwest wind farm projects because of concerns onits interference with military radar.
